FIELD

The present disclosure relates to pharmaceutical compositions of compounds that inhibit Spleen Tyrosine Kinase (Syk) activity. The disclosure also relates to methods of preparing such pharmaceutical compositions, and the use of such pharmaceutical compositions in treating subjects with various diseases, including cancer and inflammatory conditions.

BACKGROUND

A number of imidazopyrazine compounds are under investigation for inhibiting Spleen Tyrosine Kinase (Syk) activity. Syk is a non-receptor tyrosine kinase that plays critical roles in immunoreceptor- and integrin-mediated signaling in a variety of cell types, including B-cells, macrophages, monocytes, mast cells, eosinophils, basophils, neutrophils, dendritic cells, T-cells, natural killer cells, platelets, and osteoclasts.

Syk has been reported to play an important role in signaling through the B-cell receptor, known to be an important survival signal in B-cells. As such, inhibition of Syk activity may be useful for treating certain types of cancer, including B-cell lymphoma and leukemia. Additionally, the inhibition of Syk activity is believed to be useful for treating other diseases and conditions, including inflammatory diseases (e.g., rheumatoid arthritis), allergic disorders and autoimmune diseases.

One such compound that has been found to inhibit Syk activity is represented by Formula I:

or a pharmaceutically acceptable salt thereof. This compound and its synthesis have been described in U.S. Pat. Nos. 8,450,321 and 8,455,493, which are hereby incorporated herein by reference in their entirety, and are hereby incorporated by reference specifically with reference to Examples 1 and 2.

Early clinical programs have focused on oral administration of the compound of Formula I. What is desired is an oral formulation of the compound of Formula I that has low inter-subject variability, extended dose linearity, and low drug-drug-interaction. Additionally, what is desired is a commercially viable manufacturing process for the formulation of the compound of Formula I. For example, what is desired is a process that has little or no variability when different batches of the active pharmaceutical ingredient are produced, and that can be easily handled and manufactured on a commercial scale. What is also desired is a formulation that is both chemically and physically stable during the manufacturing process and upon storage.

In certain embodiments, less than about 50%, less than about 40%, less than about 30%, less than about 20%, about 15%, about 10%, about 5%, about 4%, about 3%, about 2%, or about 1% of the compound of Formula I present in the pharmaceutical composition is other than polymorph Form 3 as described above.

In certain aspects, provided is a stable pharmaceutical composition comprising at least one polymorph of a pharmaceutically acceptable salt of the compound of Formula I, or a hydrate thereof, and at least one pharmaceutically acceptable carrier. In some embodiments, provided is a stable pharmaceutical composition comprising a polymorph of a pharmaceutically acceptable salt of the compound of Formula I, and at least one pharmaceutically acceptable carrier. In one variation, provided is a stable pharmaceutical composition comprising Form 3 (which is a polymorph of a monohydrate, bis-mesylate salt of Formula IA), and at least one pharmaceutically acceptable carrier.

The pharmaceutically acceptable salt of the compound of Formula I, or a hydrate thereof, can be crystalline or non-crystalline, or can exhibit short-range order as in a semi-crystalline solid. The crystallinity of the salt, or hydrate thereof, in the compositions (e.g., the pharmaceutical compositions and formulations) may depend on the method of formulation and processing (e.g., incorporation of the salt, or hydrate thereof, by spray drying and/or dry granulation).

Crystalline Salt

In some embodiments of the compositions (including without limitation the pharmaceutical compositions), methods of making and using such compositions, kits, unit dosage forms and articles of manufacture provided herein, the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, is crystalline. In a variation of the foregoing embodiment, the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, may be: (i) a mesylate salt of a compound of Formula I, or a hydrate thereof; or (ii) a bis-mesylate salt of a compound of Formula I, or a hydrate thereof; (iii) a hydrate, bis-mesylate salt of a compound of Formula I; or (iv) a monohydrate bis-mesylate salt of a compound of Formula I, wherein the pharmaceutically acceptable salt, or a hydrate thereof, in each variation is crystalline. For example, a crystalline salt as described in the foregoing embodiments may be present in a tablet prepared by formulating polymorph Form 3 as a granulation.

The term “crystalline”, in one variation, refers to a solid phase in which the material has a regular ordered internal structure at the molecular level and gives a distinctive X-ray diffraction pattern with defined peaks. The term “crystalline”, in another variation, may also refer to a state in which the material exhibits long range order at the molecular level and gives a distinctive X-ray diffraction pattern with defined peaks. Such materials when heated sufficiently will also exhibit the properties of a liquid, but the change from solid to liquid is characterized by a phase change, typically first order (melting point).

In certain embodiments, the pharmaceutically acceptable salt of the compound of Formula I, or a hydrate thereof, is substantially crystalline. In a variation of the foregoing embodiment, the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, may be: (i) a mesylate salt of a compound of Formula I, or a hydrate thereof; or (ii) a bis-mesylate salt of a compound of Formula I, or a hydrate thereof; (iii) a hydrate, bis-mesylate salt of a compound of Formula I; or (iv) a monohydrate bis-mesylate salt of a compound of Formula I, wherein the pharmaceutically acceptable salt, or a hydrate thereof, in each variation of the composition is substantially crystalline.

In some embodiments, a compound (e.g., a pharmaceutically acceptable salt or a hydrate thereof) that is substantially crystalline has greater than 50%; or greater than 55%; or greater than 60%; or greater than 65%; or greater than 70%; or greater than 75%; or greater than 80%; or greater than 85%; or greater than 90%; or greater than 95%, or greater than 99% of the compound (e.g., a pharmaceutically acceptable salt or a hydrate thereof) present in a composition in crystalline form. In other embodiments, a compound (e.g., a pharmaceutically acceptable salt or a hydrate thereof) that is substantially crystalline has no more than about 20%, or no more than about 10%, or no more than about 5%, or no more than about 2% of the compound in non-crystalline form. In other embodiments, a compound (e.g., a pharmaceutically acceptable salt or a hydrate thereof) that is substantially crystalline has no more than about 20%, or no more than about 10%, or no more than about 5%, or no more than about 2% of the compound in amorphous form.

Non-Crystalline

In other embodiments of the compositions (including without limitation the pharmaceutical compositions), methods of making and using such compositions, kits, unit dosage forms and articles of manufacture provided herein, the pharmaceutically acceptable salt of a compound of Formula I is non-crystalline. In a variation of the foregoing embodiment, the pharmaceutically acceptable salt of a compound of Formula I, may be: (i) a mesylate salt of a compound of Formula I; or (ii) a bis-mesylate salt of a compound of Formula I, wherein the pharmaceutically acceptable salt in each variation is crystalline. For example, a non-crystalline salt as described in the foregoing embodiments may be present in a spray-dried powder prepared from a compound of Formula I, or a pharmaceutically acceptable salt thereof, or hydrate thereof.

The term “non-crystalline” refers to a state in which the material lacks long range order at the molecular level. One of skill in the art would recognize that such materials do not typically exhibit sharp peaks in their X-ray diffraction patterns.

In some embodiments, the pharmaceutically acceptable salt of a compound of Formula I or hydrate thereof (including, for example, a bis-mesylate salt of Formula IA) formulated as a solid dispersion formulation (as discussed in further detail below) is substantially non-crystalline. In certain embodiment, a compound, or a pharmaceutically acceptable salt thereof, or hydrate thereof, that is substantially non-crystalline has greater than 50%; or greater than 55%; or greater than 60%; or greater than 65%; or greater than 70%; or greater than 75%; or greater than 80%; or greater than 85%; or greater than 90%; or greater than 95%, or greater than 99% of the compound, or a pharmaceutically acceptable salt thereof, present in a composition in non-crystalline form. In other embodiments, a compound, or a pharmaceutically acceptable salt thereof, or hydrate thereof, that is substantially non-crystalline has no more than about 20% crystallinity, or no more than about 10% crystallinity, or no more than about 5% crystallinity, or no more than about 2% crystallinity.

Amorphous

In some embodiments of the pharmaceutical composition, the pharmaceutically acceptable salt of the compound of Formula I, or a pharmaceutically acceptable salt thereof, or hydrate thereof, may be amorphous. In certain embodiments, the bis-mesylate salt of Formula IA may be amorphous.

The term “amorphous” refers to a state in which the material lacks order (e.g., long range order) at the molecular level and, depending upon temperature, may exhibit the physical properties of a solid or a liquid. Typically such materials do not give distinctive X-ray diffraction patterns and, while exhibiting the properties of a solid, are more formally described as a liquid. Upon heating, a change from solid to liquid properties occurs which is characterized by a change of state, typically second order (e.g., glass transition).

For example, in one embodiment, the pharmaceutically acceptable salt of a compound of Formula I or hydrate thereof (including, for example, a bis-mesylate salt of Formula IA) formulated as a solid dispersion formulation (as discussed in further detail below) is substantially amorphous. In some embodiments, a compound that is substantially amorphous has greater than 50%; or greater than 55%; or greater than 60%; or greater than 65%; or greater than 70%; or greater than 75%; or greater than 80%; or greater than 85%; or greater than 90%; or greater than 95%, or greater than 99% of the compound present in a composition in amorphous form. In other embodiments, a compound that is substantially amorphous has no more than about 20% crystallinity, or no more than about 10% crystallinity, or no more than about 5% crystallinity, or no more than about 2% crystallinity.

Deuterated Compounds

Any formula or structure given herein, including a compound of Formula I and pharmaceutically acceptable salts thereof (including, for example, the mono-mesylate and the bis-mesylate salts), or a hydrate thereof, is also contemplated as an isotopically labeled form of the compounds, or salts, or hydrates thereof. Thus, although the unlabeled forms of compounds are provided, it is understood that the present disclosure also contemplates isotopically labeled compounds, even though such isotopes are not explicitly depicted. Isotopically labeled compounds, or salts, or hydrates thereof have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as, but not limited to ²H (deuterium, D), ³H (tritium), ¹¹C, ¹³C, ¹⁴C, ¹⁵N, ¹⁸F, ³¹P, ³²P, ³⁵S, ³⁶C and ¹²⁵I. For instance, isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as, but not limited to ²H (deuterium, D), ³H (tritium), ¹¹C, ¹³C, ¹⁴C, ¹⁵N, and ³⁵S may be incorporated into a compound of formula I, including a salt (e.g. a mesylate salt) of a compound of formula I, or a hydrate thereof. Various isotopically labeled compounds, or salts, or hydrates thereof of the present disclosure, for example those into which radioactive isotopes such as ³H, ¹³C and ¹⁴C are incorporated. Such isotopically labeled compounds or salts thereof may be useful in metabolic studies, reaction kinetic studies, detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays or in radioactive treatment of subjects.

The disclosure also includes a compound of Formula I and pharmaceutically acceptable salts thereof (including, for example, the mono-mesylate and the bis-mesylate salts), or a hydrate thereof, in which from 1 to n hydrogens attached to a carbon atom is/are replaced by deuterium, in which n is the number of hydrogens in the molecule. Such compounds may exhibit increased resistance to metabolism and are thus useful for increasing the half life of a compound of Formula I, or pharmaceutically acceptable salts thereof, or hydrates thereof (including a bis-mesylate salt of Formula IA or IB, or a hydrate thereof; or a hydrate, bis-mesylate of Formula IC or ID) when administered to a mammal. See, for example, Foster, “Deuterium Isotope Effects in Studies of Drug Metabolism”, Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compounds are synthesized by means well known in the art, for example by employing starting materials in which one or more hydrogens have been replaced by deuterium.

Deuterium labeled or substituted therapeutic compounds of the disclosure (including salts or hydrates thereof) may have improved DMPK (drug metabolism and pharmacokinetics) properties, relating to absorption, distribution, metabolism and excretion (ADME). Substitution with heavier isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life, reduced dosage requirements and/or an improvement in therapeutic index. An ¹⁸F labeled compound may be useful for PET or SPECT studies. Isotopically labeled compounds of this disclosure and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent. It is understood that deuterium in this context is regarded as a substituent in the compound of Formula I and pharmaceutically acceptable salts thereof (including, for example, the mono-mesylate and the bis-mesylate salts), or hydrates thereof.

The concentration of such a heavier isotope, specifically deuterium, may be defined by an isotopic enrichment factor. In the compounds of this disclosure any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen”, the position is understood to have hydrogen at its natural abundance isotopic composition. Accordingly, in the compounds or salts thereof of this disclosure any atom specifically designated as a deuterium (D) is meant to represent deuterium.

It should further be understood that, in other embodiments, the pharmaceutical composition may comprise one or more additional carriers to improve flow, compression, hardness, taste, and tablet performance.

Pharmaceutically Acceptable Polymers

While the pharmaceutically acceptable carriers used in the pharmaceutical compositions provided may be described functionally, the pharmaceutically acceptable carriers may also be described structurally. Thus, the pharmaceutically acceptable carriers in one aspect are pharmaceutically acceptable polymers.

Provided is a composition (e.g., pharmaceutical composition) comprising a mesylate salt of a compound of Formula I, or a hydrate thereof, and at least one, at least two, or at least three pharmaceutically acceptable polymer(s). In the foregoing embodiment, the mesylate salt of the compound of Formula I, or a hydrate thereof, may be a mono-mesylate salt of the compound of Formula I, or a hydrate thereof; or a bis-mesylate salt of the compound of Formula I, or a hydrate thereof; or a hydrate, bis-mesylate salt of the compound of Formula I; or a monohydrate, bis-mesylate salt of the compound of Formula I.

The term “polymer” refers to a chemical compound or mixture of compounds consisting of repeating structural units, which may be created through a process of polymerization. Suitable polymers useful in this invention are described throughout. The term “pharmaceutically acceptable polymer” refers to a polymer that does not have properties that would cause a reasonably prudent medical practitioner to avoid administration of the material to a subject (e.g., human), taking into consideration the disease or conditions to be treated and the respective route of administration.

In certain variations, the composition (e.g., pharmaceutical composition) comprises a mesylate salt of a compound of Formula I (including, for example, a mono-mesylate or bis-mesylate salt), and one, two, three, or four pharmaceutically acceptable polymer(s). In one variation, the composition (e.g., pharmaceutical composition) comprises a mesylate salt of a compound of Formula I (including, for example, a mono-mesylate or bis-mesylate salt), at least one pharmaceutically acceptable polymer, and at least one, at least two, or at least three additional pharmaceutically acceptable carrier(s). In other variations, the composition (e.g., pharmaceutical composition) comprises a mesylate salt of a compound of Formula I (including, for example, a mono-mesylate or bis-mesylate salt), one, two, three, or four pharmaceutically acceptable polymer(s), and at least one, at least two, or at least three additional pharmaceutically acceptable carrier(s).

In some embodiments of the composition (e.g., pharmaceutical composition), at least one of the pharmaceutically acceptable polymers is hydroxypropylmethylcellulose (also known in the art as HPMC or by other common names such as hypromellose). HPMC is commonly used in the art as a pharmaceutically acceptable carrier in sustained release formulations, and may also be used for immediate release formulations as described herein.

It should be understood by a skilled artisan that the active agent may be formulated for sustained release or immediate release. A “sustained release formulation” is a formulation which is designed to slowly release an active agent in the subject over an extended period of time, whereas an “immediate release formulation” is a formulation which is designed to quickly release an active agent in the subject over a shortened period of time. In some cases, the immediate release formulation may be coated such that the active agent is only released once it reached the desired target in the subject, for example, in the stomach.

In another embodiment of the pharmaceutical composition, a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, is formulated for immediate release. In the foregoing embodiment, the pharmaceutically acceptable salt of the compound of Formula I, or a hydrate thereof, may be a mesylate salt of the compound of Formula I; or a mono-mesylate salt of the compound of Formula I, or a hydrate thereof; or a bis-mesylate salt of the compound of Formula I, or a hydrate thereof; or a hydrate, bis-mesylate salt of the compound of Formula I; or a monohydrate, bis-mesylate salt of the compound of Formula I.

The use of hydroxypropylmethylcellulose in such immediate release formulation was observed to increase bioavailability of the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, administered to the subject (e.g., a human) compared to a formulation of a compound of Formula I without the use of hydroxypropylmethylcellulose. Thus, in some aspects, provided is a method of increasing bioavailability of a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, comprising administering to a human in need thereof a composition comprising (i) a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, and (ii) hydroxypropylmethylcellulose, to increase bioavailability of the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof. In one variation, bioavailability is increased in the human compared to administering to the human a composition comprising a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, in which hydroxypropylmethylcellulose is absent. In some embodiments, the composition is a tablet.

In some variations of the foregoing methods of increasing bioavailability, the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, is a bis-mesylate salt of a compound of Formula I; and in one variation, the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, is a monohydrate, bis-mesylate salt of a compound of Formula I.

In some instances, hydroxypropylmethylcellulose was observed to prolong supersaturation of the pharmaceutically acceptable salt of a compound of Formula I (including, for example, a mesylate salt of a compound of Formula I), or a hydrate thereof. Thus, in some aspects, provided is a method of prolonging supersaturation of a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, in a composition, comprising adding hydroxypropylmethylcellulose to a composition comprising a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, to prolong supersaturation. In one variation, supersaturation of a compound of Formula I, or a hydrate thereof in the composition is prolonged compared to a composition comprising a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, in which hydroxypropylmethylcellulose is absent.

In some variations of the foregoing methods to prolong supersaturation, the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, is a bis-mesylate salt of a compound of Formula I; and in one variation, the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, is a monohydrate, bis-mesylate salt of a compound of Formula I. In some embodiments, supersaturation is prolonged over an hour, which gives a compound of Formula I a longer window to be absorbed in vivo. In some embodiments, the composition is a feed solution for spray drying.

In other instances, hydroxypropylmethylcellulose was observed to minimize crystallization of the pharmaceutically acceptable salt of a compound of Formula I (including, for example, a mesylate salt of a compound of Formula I), or a hydrate thereof, when combined with the pharmaceutically acceptable salt of a compound of Formula I (including, for example, a mesylate salt of a compound of Formula I), or a hydrate thereof in a solid dispersion. Thus, in other aspects, provided is a method of minimizing crystallization of a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, in a composition, comprising adding hydroxypropylmethylcellulose to a composition comprising a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, to minimize crystallization compared to a composition comprising a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, in which hydroxypropylmethylcellulose is absent. In one variation, crystallization of a compound of Formula I, or a hydrate thereof, in the composition is minimized compared to a composition comprising a pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, in which hydroxypropylmethylcellulose is absent.

In some variations of the foregoing methods to minimize crystallization, the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, is a bis-mesylate salt of a compound of Formula I; and in one variation, the pharmaceutically acceptable salt of a compound of Formula I, or a hydrate thereof, is a monohydrate, bis-mesylate salt of a compound of Formula I. In some embodiments, crystallization is prevented for more than nine months under 40° C./75% RT open conditions. In some embodiments, the composition is a feed solution for spray drying.

In one variation of the pharmaceutical composition, the bis-mesylate salt of Formula IA is formulated for immediate release. While hydroxypropylmethylcellulose is commonly used in the art for sustained release formulations, the use of hydroxypropylmethylcellulose in an immediate release formulation of the bis-mesylate salt of Formula IA was observed to increase bioavailability of the bis-mesylate salt of Formula IA administered to the subject compared to a formulation without the use of hydroxypropylmethylcellulose. In some instances, hydroxypropylmethylcellulose was observed to prolong supersaturation of a compound of Formula I, or a pharmaceutically acceptable salt thereof (including, for example, the mono-mesylate or bis-mesylate salt). In other instances, hydroxypropylmethylcellulose was observed to minimize crystallization of a compound of Formula I, or a pharmaceutically acceptable salt thereof (including, for example, the mono-mesylate or bis-mesylate salt) from a solution of a compound of Formula I, or a pharmaceutically acceptable salt thereof (including, for example, a mono-mesylate or bis-mesylate salt thereof).

In one variation, at least one of the pharmaceutically acceptable polymers is any pharmaceutically acceptable polymer (a) capable of prolonging supersaturation of a compound of Formula I, or a pharmaceutically acceptable salt thereof (including, for example, the mono-mesylate or bis-mesylate salt); (b) capable of minimizing crystallization of a compound of Formula I, or a pharmaceutically acceptable salt thereof (including, for example, the mono-mesylate or bis-mesylate salt) from a solution of a compound of Formula I, or a pharmaceutically acceptable salt thereof (including, for example, the mono-mesylate or bis-mesylate salt); or both (a) and (b).

In some embodiments, in addition to the mesylate salt (including, for example, the bis-mesylate salt) of a compound of Formula I, or a hydrate thereof, and hydroxypropylmethylcellulose, the pharmaceutical composition may further comprise one or more additional pharmaceutically acceptable polymers. Such additional polymers may include, for example, block copolymers and naturally occurring polymers. Suitable additional polymers may, for example, be selected from the group consisting of crospovidone, povidone, poloxamer, microcrystalline cellulose, and any combinations thereof.

In other embodiments, in addition to the mesylate salt (including, for example, the bis-mesylate salt) of a compound of Formula I, or a hydrate thereof, hydroxypropylmethylcellulose and one or more additional polymers, the pharmaceutical composition may further comprise one or more other pharmaceutically acceptable carriers. Such other carriers may be selected from the group consisting of lactose monohydrate, mannitol, sodium lauryl sulfate, colloidal silicon dioxide, magnesium stearate, and any combinations thereof.

It should be understood that the amount of individual components (e.g., the active agent and pharmaceutically acceptable carriers) of the pharmaceutical composition may vary depending on several factors, including the unit dosage form (e.g., a tablet incorporating the active agent by spray drying and/or dry granulation).

The term “% w/w” as used herein refers to the weight of a component based on the total weight of a composition comprising the component. For example, if component A is present in an amount of 50% w/w in a 100 mg composition, component A is present in an amount of 50 mg.

As used herein, “a” means one or more unless indicated otherwise.

The use of the term “about” includes and describes the value or parameter per se. For example, “about x” includes and describes “x” per se. In some embodiments, the term “about” when used in association with a measurement, or used to modify a value, a unit, a constant, or a range of values, refers to variations of ±10%. For example, “about 2:8” in some embodiments includes 1.8-2.2:7.2-8.8.

Table A below provides exemplary weight percent of certain components (e.g., active agent and carriers) for use in the formulations.

Thus, in some embodiments, the pharmaceutical compositions are tablets comprising a solid dispersion; or in certain embodiments, the pharmaceutical compositions are tablets comprising a spray-dried solid dispersion.

A skilled artisan would recognize suitable methods and techniques to prepare a solid dispersion and a tablet comprising such solid dispersion. Exemplary methods and techniques to prepare such solid dispersions include melt-extrusion, spray-drying, lyophilization, and solution-evaporation. In some embodiments, the solid dispersion is prepared by spray drying. For example, the mesylate salt (including, for example, the mono-mesylate or bis-mesylate salt) of a compound of Formula I and at least one pharmaceutically acceptable polymer (including, for example, HPMC) are dissolved, or at least partially dissolved, in water, and spray dried to form a solid dispersion. The solid dispersion may then be blended with other pharmaceutically acceptable carriers, and then dried granulated, followed by compression and coating. An exemplary manufacturing process for preparing a solid dispersion and tablet of the bis-mesylate salt of a compound of Formula I is described in Example C1 below.

In one aspect, provided herein is a method of manufacturing a tablet, comprising:

a) forming spray-dried powder from a feed solution, wherein the feed solution comprises: (i) a compound of Formula I, or a cation thereof; (ii) methanesulfonic acid, or an anion thereof; (iii) at least one pharmaceutically acceptable carrier; and (iv) water;

It should be understood that various forms of a compound of Formula I, or a salt or hydrate thereof, may be used to form the feed solution that is spray dried to manufacture solid dispersion particles. In certain embodiments, a compound of Formula I (e.g., as a free base), or a mono-mesylate or bis-mesylate salt of a compound of Formula I, or a hydrate thereof, or any combinations thereof, may be used to prepare the feed solution. For example, the starting material used for preparing the feed solution (e.g., for forming the solid dispersion) may include one or more forms of a mesylate salt of a compound of Formula I, or in certain embodiments, a bis-mesylate salt of Formula IA.

Provided is also a tablet (e.g., a spray-dried solid dispersion tablet) produced according to any of the foregoing methods.

(ii) at least one pharmaceutically acceptable carrier; and

(iii) water to form a feed solution.

In embodiments where the mesylate salt, or a hydrate thereof, is combined with the at least one pharmaceutically acceptable carrier and water to form the feed solution, the method further comprises combining methanesulfonic acid with the feed solution.

In one variation, the feed solution may be prepared by combining a compound of Formula I and methanesulfonic acid. In another variation, the feed solution may be prepared by combining a mesylate salt of a compound of Formula I and additional methanesulfonic acid. In one variation, the mesylate salt may be a mono-mesylate salt or a bis-mesylate salt, or a combination thereof. In another variation, the mesylate salt is a monohydrate, bis-mesylate salt of a compound of Formula I. In another variation, the mesylate salt is polymorph Form 3, a monohydrate, bis-mesylate salt of a compound of Formula I.

In some embodiments, the methanesulfonic acid, or an anion thereof, and the compound of Formula I, or a cation thereof, are present in the feed solution in a molar ratio of between 2:1 and 3:1, or between 2:1 and 2.7:1, or between 2.1:1 and 2.5:1, or between 2.2:1 and 2.4:1, or about 2.3:1, or about 2.4:1. In another variation, the molar ratio of the methanesulfonic acid or an anion thereof, to the compound of Formula I or a cation thereof, is greater than 1:1 and less than 2:1.

In other embodiments, the feed solution is prepared with at least 1% w/w, or between 1% w/w and 10% w/w, or about 5% w/w of the compound of Formula I, or a cation thereof.

In other embodiments, the compound of Formula I, or a cation thereof, and the water are present in the feed solution in a molar ratio of between 1:1 to 1:2, or about 1:1.5.

Spray-Dried Powder

The feed solution described herein may undergo spray drying to form a spray-dried powder, which is also known as a spray-dried solid dispersion.

Provided herein is also a spray-dried powder, comprising:

(i) a bis-mesylate salt of a compound of Formula I:

and

(ii) at least one pharmaceutically acceptable carrier.

In some embodiments of the spray-dried powder, the bis-mesylate salt is a bis-mesylate salt of the compound of Formula I.

In other embodiments, the spray-dried powder further comprises additional methanesulfonic acid, or an anion thereof.

In other aspects, provided herein is also a spray-dried powder, comprising:

(i) a mesylate salt of a compound of Formula I:

wherein the mesylate salt comprises a cation of the compound of Formula I and a mesylate anion; and

(ii) at least one pharmaceutically acceptable carrier.

In one variation of the foregoing aspect of the spray-dried powder, the molar ratio of the mesylate anion to the cation of the compound of Formula I is at least 1:1, or between 1:1 and 3.3:1, between 1.9:1 and 3.3:1, between 1.9:1 and 2.5:1, between 1.9:1 and 2.4:1, between 2:1 to 3.3:1, between 2:1 and 3:1, or between 2:1 and 2.7:1, or between 2.1:1 and 2.5:1, or between 2.2:1 and 2.4:1, or about 2.3:1, or about 2.4:1. In another variation, the molar ratio of the mesylate anion to the cation of the compound of Formula I is greater than 1:1 and less than 2:1. In yet another variation, the molar ratio of the mesylate anion to the cation of the compound of Formula I is greater than 2:1.

When such molar ratio in the spray-dried powder is greater than 2:1, the spray-dried powder was unexpectedly observed to exhibit improved stability. For example, improved stability may entail minimizing crystallization of the spray-dried powder (e.g., minimizing crystallization of the other polymorphic forms, such as Form 7 of the bis-mesylate salt of a compound of Formula I). For example, when such molar ratio is 2.3:1 or greater, for example, between 2.3:1 and 2.5:1, the spray-dried solid dispersion may remain stable for at least two months at room temperature and 75% relative humidity.

In yet other aspects, provided herein is a spray-dried powder comprising:

or a cation thereof;

(ii) methanesulfonic acid, or an anion thereof; and

In another variation, the molar ratio of the methanesulfonic acid or an anion thereof, to the compound of Formula I or a cation thereof, is greater than 1:1 and less than 2:1. In yet another variation, the molar ratio of the methanesulfonic acid or an anion thereof, to the compound of Formula I or a cation thereof, is greater than 2:1.

In certain embodiments, the spray-dried powder is characterized by an X-ray diffraction pattern comprising 2θ-reflections (±0.2°) at 6.3 and between 26.1 to 26.6. It should be understood that +0.2° can also be expressed as “plus or minus 0.2 degrees 2θ”.

In certain embodiments of the spray-dried powder, at least one pharmaceutically acceptable carrier is a precipitation inhibitor. In one variation, the precipitation inhibitor is hydroxypropylmethylcellulose (HPMC). In another variation, the precipitation inhibitor is copovidone.

The spray-dried solid dispersion tablet is formed from the spray-dried powder by dry granulation and compression as described herein. For example, in certain embodiments, the spray-dried powder and pharmaceutically acceptable carriers are blended, dry granulated, milled, and compressed to form a tablet, which may be coated and packaged.

Methods of Use

Provided is also the use of the pharmaceutical compositions (including, for example, the tablets and unit dosage forms) described in the present disclosure to selectively or specifically inhibit Syk activity therapeutically or prophylactically. The method comprises administering the pharmaceutical composition to an individual in need thereof in an amount sufficient to inhibit Syk activity. The method can be employed to treat subjects (e.g., humans) suffering from, or subject to, a condition whose symptoms or pathology is mediated by Syk expression or activity.

In one aspect, provided is a method of treating a human in need thereof, comprising administering the pharmaceutical compositions (including, for example, the tablets and unit dosage forms) described herein to the human.

“Treatment” or “treating” is an approach for obtaining beneficial or desired results including clinical results. Beneficial or desired clinical results may include one or more of the following:

a) inhibiting the disease or condition (e.g., decreasing one or more symptoms resulting from the disease or condition, and/or diminishing the extent of the disease or condition);

b) slowing or arresting the development of one or more clinical symptoms associated with the disease or condition (e.g., stabilizing the disease or condition, preventing or delaying the worsening or progression of the disease or condition, and/or preventing or delaying the spread (e.g., metastasis) of the disease or condition); and/or

c) relieving the disease, that is, causing the regression of clinical symptoms (e.g., ameliorating the disease state, providing partial or total remission of the disease or condition, enhancing effect of another medication, delaying the progression of the disease, increasing the quality of life, and/or prolonging survival.

“Prevention” or “preventing” means any treatment of a disease or condition that causes the clinical symptoms of the disease or condition not to develop. Compounds may, in some embodiments, be administered to a subject (including a human) who is at risk or has a family history of the disease or condition.

Subjects

Any of the methods of treatment provided may be used to treat a subject who has been diagnosed with or is suspected of having a cancer, an allergic disorder and/or an autoimmune and/or inflammatory disease, and/or an acute inflammatory reaction.

In some of the embodiments of any of the methods provided herein, the subject is a human who is at risk of developing a cancer (e.g., a human who is genetically or otherwise predisposed to developing a cancer) and who has or has not been diagnosed with the cancer. As used herein, an “at risk” subject is a subject who is at risk of developing cancer (e.g., a hematologic malignancy). The subject may or may not have detectable disease, and may or may not have displayed detectable disease prior to the treatment methods described herein. An at risk subject may have one or more so-called risk factors, which are measurable parameters that correlate with development of cancer, such as described herein. A subject having one or more of these risk factors has a higher probability of developing cancer than an individual without these risk factor(s).

These risk factors may include, for example, age, sex, race, diet, history of previous disease, presence of precursor disease, genetic (e.g., hereditary) considerations, and environmental exposure. In some embodiments, a subject at risk for cancer includes, for example, a subject whose relatives have experienced this disease, and those whose risk is determined by analysis of genetic or biochemical markers. Prior history of having cancer may also be a risk factor for instances of cancer recurrence.

Provided herein are also methods for treating a subject (e.g., a human) who exhibits one or more symptoms associated with cancer (e.g., a hematologic malignancy). In some embodiments, the subject is at an early stage of cancer. In other embodiments, the subject is at an advanced stage of cancer.

In some embodiments, the subject (e.g., a human) has a cancer responsive to Syk activity. In another embodiment, the human has a solid cancer tumor which expresses Syk. In some embodiments, the human has a 17p deletion, a TP53 mutation, NOTCH1, a SF3B1 mutation, a 11q deletion, or any combination thereof.

In another aspect, provided herein are methods for treating a subject (e.g., a human) who is “refractory” to a cancer treatment or who is in “relapse” after treatment for cancer (e.g., a hematologic malignancy). A subject “refractory” to an anti-cancer therapy means they do not respond to the particular treatment, also referred to as resistant. The cancer may be resistant to treatment from the beginning of treatment, or may become resistant during the course of treatment, for example after the treatment has shown some effect on the cancer, but not enough to be considered a remission or partial remission. A subject in “relapse” means that the cancer has returned or the signs and symptoms of cancer have returned after a period of improvement, e.g. after a treatment has shown effective reduction in the cancer, such as after a subject is in remission or partial remission.

In some embodiments, the subject may be a human who is (i) refractory to at least one anti-cancer therapy, or (ii) in relapse after treatment with at least one anti-cancer therapy, or both (i) and (ii).

Example A1: Synthesis of Polymorph Form 3

Methods for generally making various forms of the compound of Formula I may be found in U.S. Pat. Nos. 8,450,321 and 8,455,493. The following is a method for producing polymorph Form 3, which is a polymorph of a monohydrate, bis-mesylate salt of a compound of Formula I (and may also be described as a polymorph of a monohydrate of the compound of Formula IA shown in the reaction scheme below).

A compound of Formula I (1.0 X) was added to Reactor A. Methanesulfonic acid (0.56 X, 2.40 eq), water (4 X, 4 V) and acetone (3.2 X, 4 V) were added to Reactor B. The contents of Reactor B were added to Reactor A while maintaining the temperature in Reactor A below 35° C. After the solids dissolved, the contents of Reactor A were transferred to Reactor B. Reactor A was rinsed with water (1 X, 1 V) and acetone (0.8 X, 1 V), and transferred to Reactor B. The temperature of Reactor B was adjusted to 19-25° C. Under high agitation, acetone (11.9 X, 15 V) was added to Reactor B. The temperature of Reactor B was adjusted to 0-6° C. and the contents of Reactor B were mixed for 5 h, then filtered, and rinsed with acetone (4.0 X, 5 V) to provide polymorph Form 7. Form 7 was dried under vacuum at 60° C. until constant weight was achieved. Representative patterns of an XRPD of polymorph Form 7 are shown in FIGS. 1C and 1D.

The isolated polymorph Form 7 was added to polymorph Form 3 seeds of a compound of Formula IA (0.01 X, 1 mol %) in Reactor B. Acetone (15.4 X, 19.5 V), and water (0.5 X, 0.5 V) were added to Reactor B and mixed at 19-25° C. until polymorph Form 7 was converted to Form 3. The conversion was monitored by XRPD or DSC. The contents of Reactor B was filtered, rinsed with acetone (2.4 X, 3 V) and dried under vacuum at 60° C. until constant weight was achieved. Representative patterns of an XRPD of polymorph Form 3 are shown in FIGS. 1A and 1B.

Example A2: Alternative Synthesis of Polymorph Form 3

The following is a method for producing polymorph Form 3, a monohydrate, bis-mesylate salt of a compound of Formula I (which may also be described as a polymorph of a monohydrate of the compound of Formula IA shown in the reaction scheme below).

Polymorph Form 7 was obtained as described in Example A1.

The isolated polymorph Form 7 was added to polymorph Form 3 seeds of a compound of Formula IA (0.01 X, 1 mol %) in Reactor B. Acetone (15.0 X, 19.0 V), and water (1.0 X, 1.0 V) were added to Reactor B. The contents of the Reactor B were heated to reflux (about 55° C.) until polymorph Form 7 was converted to Form 3. The conversion was monitored by XRPD or DSC. The contents of Reactor B was a slurry and was cooled to 19-25° C., then filtered, rinsed with acetone (2.4 X, 3 V) and dried under vacuum at 60° C. until constant weight is achieved to provide the polymorph Form 3. Representative patterns of an XRPD of polymorph Form 3 are shown in FIGS. 1A and 1B.

The following is a method for producing polymorph Form 3, a monohydrate, bis-mesylate salt of a compound of Formula I (which may also be described as a polymorph of a monohydrate of the compound of Formula IA shown in the reaction scheme below) from a compound of Formula I (as a the free base). The described method uses a single reactor in the conversion of a compound of Formula I to polymorph Form 3, and does not require isolation of a compound intermediate.

A compound of Formula I (1.0X) was added to acetone (14.2X, 18V) in Reactor A and mixed. Water (0.8X, 0.8V) was added to Reactor A, followed by methanesulfonic acid, (0.48 X, 2.05 eq). Acetone (0.9 X, 1.2 V) was pumped through to rinse the lines forward to Reactor A with acetone. The contents of Reactor A were heated to reflux (about 55° C.) for about 2 hours. Polymorph Form 3 seeds (0.015 X, 1 mol %) were added to Reactor A and the contents mixed at reflux to convert a compound of Formula IA to polymorph Form 3. The conversion was monitored by XRPD. The contents of the reactor were cooled to 19-25° C., filtered, rinsed with acetone (4.0 X, 5 V), and dried under vacuum at 60° C. Representative patterns of an XRPD of polymorph Form 3 are shown in FIGS. 1A and 1B.

Example A4: Alternative Synthetic Route for Polymorph Form 3 Via Mono-MSA Intermediate

This example provides a description of the synthesis of polymorph Form 3 (which is a polymorph of a monohydrate, bis-MSA salt of a compound of Formula I) from a mono-MSA salt of a compound of Formula I.

Formic acid (3.7 X) is charged to a reaction vessel and combined with ethyl acetate (9.7 X). The contents are agitated and adjusted to about 19 to 25° C. The mono-MSA compound of Formula I (1.0 X) is charged portion-wise while maintaining the content temperature at about 19 to 25° C. The contents are agitated at about 19 to 25° C. until all solids dissolve.

To the above contents is added a solution of ethyl acetate (0.6 X) and methanesulfonic acid (0.169 X, corrected for MSA content and water present in the mono-MSA compound) prepared in a separate reaction vessel. The resulting mixture is agitated at about 19 to 25° C. for about 24 h. The reaction mixture is sampled and tested for MSA content by ion chromatography. Agitation is continued until the desired range of MSA content is achieved. Upon reaction completion, the contents of the reaction vessel are filtered, rinsed with ethyl acetate (3.6 X) and the wet filter cake is dried under vacuum at about 60° C. The dried solids are transferred back to the reaction vessel.

To the dried solids was added acetone (15.0 X) and the resulting mixture is put under maximum agitation. Water (0.50 X) is added followed by acetone (0.70 X). The mixture is agitated at about 19 to 25° C. until the form conversion to polymorph Form 3 is complete as confirmed by XRPD analysis. The solids are filtered, rinsed with acetone (2.4 X), and the wet cake is dried under vacuum at about 60° C.

Throughout this specification, various patents, patent applications and other types of publications (e.g., journal articles) are referenced. The disclosure of all patents, patent applications, and publications cited herein are hereby incorporated by reference in their entirety for all purposes.

XRPD patterns were collected with a PANalytical X'Pert PRO MPD diffractometer using an incident beam of Cu radiation produced using an Optix long, fine-focus source. An elliptically graded multilayer mirror was used to focus Cu Kα X-rays through the specimen and onto the detector. Prior to the analysis, a silicon specimen (NIST SRM 640d) was analyzed to verify the observed position of the Si 111 peak is consistent with the NIST-certified position. A specimen of the sample was sandwiched between 3-μm-thick films and analyzed in transmission geometry. A beam-stop, short antiscatter extension, and an antiscatter knife edge were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the specimen and Data Collector software v. 2.2b. The data acquisition parameters for each pattern are displayed above the image in the Data section of this report including the divergence slit (DS) before the mirror. Prominent peaks are selected from observed peaks by identifying preferably non-overlapping, low-angle peaks, with strong intensity.

An exemplary XRPD pattern of polymorph Form 3 is shown in FIG. 1A. With reference to FIG. 1A, characteristic XRPD 2θ-reflections (±0.2 degrees) for Form 3 are 13.75, 16.90, 22.88, and 26.06.

Polymorph Form 7

XRPD patterns were collected using a PANalytical X'Pert MPD Pro Powder X-Ray Diffractometer configured with reflectance stage with spinning, data acquisition range: 2-40 degrees 2θ, Copper (Cu) anode; Kα1/Kα2 radiation; tube current 40 mA; tube tension 45 kV; automatic divergence and anti-scatter slits. Samples were prepared for analysis by distributing solid material as a thin layer on a silicon holder. Each holder was mounted on a reflectance/transmittance stage and rotated during data acquisition.

An exemplary XRPD pattern of polymorph Form 7 is shown in FIG. 1C. With reference to FIG. 1C, characteristic XRPD 2θ-reflections (±0.2 degrees) for Form 7 are 4.94, 9.82, and 26.68.

Example A6: Polymorph Form 3 and Polymorph Form 7 XRPD Measurements

This example describes experimental conditions and data for XRPD measurements of polymorph Form 3 and polymorph Form 7.

X-Ray Powder Diffraction (XRPD) patterns were collected on a Bruker AXS C2 GADDS diffractometer using Cu K α radiation (40 kV, 40 mA), automated XYZ stage, laser video microscope for auto-sample positioning and a HiStar 2-dimensional area detector. X-ray optics consists of a single Göbel multilayer mirror coupled with a pinhole collimator of 0.3 mm A weekly performance check is carried out using a certified standard NIST 1976 Corundum (flat plate).

The beam divergence, i.e. the effective size of the X-ray beam on the sample, was approximately 4 mm A θ-θ continuous scan mode was employed with a sample—detector distance of 20 cm which gives an effective 2θ range of 3.2°-29.7°. Typically the sample would be exposed to the X-ray beam for 120 seconds. The software used for data collection was GADDS for XP/2000 4.1.43 and the data were analysed and presented using Diffrac Plus EVA v15.0.0.0.

Ambient conditions: Samples run under ambient conditions were prepared as flat plate specimens using powder as received without grinding. Approximately 1-2 mg of the sample was lightly pressed on a glass slide to obtain a flat surface.

Non-ambient conditions: Samples run under non-ambient conditions were mounted on a silicon wafer with heat-conducting compound. The sample was then heated to the appropriate temperature at 20° C./min and subsequently held isothermally for 1 minute before data collection was initiated.

Example A7: Polymorph Form 3 and Polymorph Form 7 XRPD Measurements

This example describes experimental conditions and data for XRPD measurements of polymorph Form 3 and polymorph Form 7.

X-Ray Powder Diffraction (XRPD) patterns were collected on a Bruker D8 diffractometer using Cu K α radiation (40 kV, 40 mA), θ-2θ goniometer, and divergence of V4 and receiving slits, a Ge monochromator and a Lynxeye detector. The instrument is performance checked using a certified Corundum standard (NIST 1976). The software used for data collection was Diffrac Plus XRD Commander v2.6.1 and the data were analysed and presented using Diffrac Plus EVA v15.0.0.0.

Samples were run under ambient conditions as flat plate specimens using powder as received. The sample was gently packed into a cavity cut into polished, zero-background (510) silicon wafer. The sample was rotated in its own plane during analysis. The details of the data collection are:

Angular range: 2 to 42 °2θ

Step size: 0.05 °2θ

Collection time: 0.5 s/step

Angular range: 3 to 30 °2θ

Step size: 0.05 °2θ

Collection time: 0.5 s/step

Example A8: Single Crystal X-Ray Structure of Polymorph Form 3

This example describes the single crystal X-ray structure of polymorph Form 3 of a monohydrate, bis-mesylate salt of a compound of Formula I.

The single crystal X-ray structure of polymorph Form 3 was determined at RT in the triclinic system, space group P-1. There was one cation of the compound of Formula I, two mesylate anions and one water molecule in the asymmetric unit and the final R1 [I>2σ(I)]=4.53%. An XRPD pattern was calculated from the crystal structure to serve as a reference for this form (FIG. 9).

Structural Features

A crystal of sufficient size and quality for analysis by single crystal X-ray diffraction was obtained by maturation between 50° C. and RT on an eight hour cycle in isopropyl acetate. The crystal was of block morphology with approximate dimensions 0.50×0.22×0.15 mm.

The structure of polymorph Form 3 was been determined as depicted in FIGS. 14A-14D. Table A1 below summarizes the sample and crystal data for polymorph Form 3.

Dry Granulation Formulation of a Bis-Mesylate Salt of Formula IA (“Formulation 1”)

The following Examples are directed to the dry granulation tablet of Form 3, the monohydrate, bis-mesylate salt of Formula IA prepared according to Example A above. It should be understood that the dry granulation tablet of the monohydrate, bis-mesylate salt of Formula IA may also be generally referred herein as “Formulation 1”.

Example B1: Manufacturing Process

This example demonstrates the preparation of the monohydrate, bis-mesylate salt of Formula IA as a tablet using a dry granulation process.

Methods

An intragranular powder blend made up of monohydrate, bis-mesylate salt of Formula IA, mannitol, HPMC, crospovidone, poloxamer 188, and colloidal silicon dioxide was prepared and then divided into four sublots for roller compaction using different compaction forces or mill screen sizes on a Gertise minipactor. The following parameters were used: smooth roller on the left and knurled roller on the right; gap at 2 mm; roller speed at 3 rpm; and the granulator at 60 rpm. Each sub-lot was mixed with extra-granular excipients (including magnesium stearate, microcrystalline cellulose and crospovidone), and the final blend was characterized for particle size, flowability by Flodex, bulk density, tap density, and compression profile. The results are summarized in Table 1 below, and FIG. 2A.

TABLE 1 Processing parameters and characterization of the final blends of Formulation 1 Mean Compact particle Bulk Force Screen size Flodex Density Tap Density (kN/cm) (mm) (μm) (mm) (g/mL) (g/mL) 7 1.0 326 12 0.55 0.75 5 313 12 0.55 0.71 3 267 12 0.52 0.67 3 1.25 299 14 0.55 0.68

At the same mill screen size, 1 mm, the particle size was observed to be dependent on the compaction force. Higher compaction force was observed to lead to bigger mean particle size as well as higher bulk density and tap density. However, the Flodex stayed the same at 12 mm for all three compaction forces tested. When mill screen size was changed to 1.25 mm while the compaction force was maintained at 3 KN, Flodex increased to 14 mm and mean particle size, bulk density and tap density all increased slightly. As shown in FIG. 2B, all blends were observed to have good compressibility although the sub-lot with higher compaction force showed slightly lower compressibility. In summary, the manufacturing process for Fm appeared robust within the ranges of the processing parameters tested. The composition of this final formulation is listed in Table 2 below.

Example B2: Disintegration Study

This Example demonstrates the effect of various disintegrants and diluents used in the dry granulation tablet prepared according to Example B1 above. The disintegrants screened in this Example include: crospovidone (Polyplasdone XL), croscarmellose sodium (Ac-Di-Sol), sodium starch glycolate (Explotab), Pharmaburst, F-melt, and Amberlite. The formulations used for the screening of disintegration (namely, Formulations Fa, Fb, Fc, Fd, Fe, and Ff) are summarized in Table 3 below.

The disintegrants were screened using standard USP disintegration apparatus in 0.01 N HCl at 37° C. The percentage of the tablet remaining after 10 minutes was visually estimated. Only the intragranular excipients of the formulation were mixed and 350 mg of the mixture was compressed into a tablet with a hardness of 8-10 Kp for this disintegration study.

The results of this disintegrant screen are summarized in Table 3 above. Crospovidone and Pharmburst formulations (i.e., Fa and Fd, respectively) was observed to have the fastest erosion.

In subsequent studies, while keeping crospovidone as the disintegrant, the following diluents were compared to the diluents used in Fa: mannitol, pregelatinized starch, calcium phosphate, and succinic acid. The formulation composition and the results of the disintegration test are summarized in Table 4 below. As seen in the table below, the mannitol formulation (Fg) showed the fastest erosion.

Example B3: Dissolution Study

This Example demonstrates the effect of various precipitation inhibitors and surfactants used in the dry granulation formulation prepared according to Example B1 above. Formulations Fk, Fl, and Fm were tested and their compositions are shown in Table 5 below.

The three formulations were tested using a USP paddle apparatus at 75 rpm with 900 mL of pH 4.5, 50 mM sodium acetate buffer with 1% cetyltrimethylammonium bromide (CTAB) as the medium, maintained at 37° C. The extent of the compound of Formula I released over time was monitored by a HPLC method.

The dissolution of the Formulation Fx 200 mg tablet (whose composition is shown in Table 6 below) was also tested using the same method.

The dissolution profiles of all four formulations are shown in FIG. 3. In Formulation Fx, 20% of the compound of Formula I was dissolved within one hour. In contrast, the dissolution of the compound of Formula I in all Formulations Fk, Fl, and Fm was 80% within one hour. Among Formulations Fk, Fl, and Fm, Fk dissolved faster and reached peak dissolution at 30 min. From 30-60 min, the amount of the compound of Formula I in Formulation Fk decreased quickly. Compared to Formulation Fk, Formulations Fl and Fm dissolved slower and reached the peak at 45 min, but the amount of the compound of Formula I in solution was not decreased before 60 min. These results indicated that HPMC is critical in maintaining the supersaturation.

Example B4: Effect of Mannitol

This Example demonstrates the effect of mannitol in the dry granulation tablet prepared according to Example B1 above. The components of the formulations used in this Example, and the amounts of such components, are summarized in Table 7 below.

The formulations were tested using standard USP disintegration apparatus in 0.01 N HCl at 37° C. The percentage of the tablet remaining at different time points was visually estimated, and the results are summarized in Table 8 below. As seen in Table 8, a lower percentage of the tablet remained over the course of 30 minutes (i.e., a greater percentage of the tablet disintegrated after 10 minutes) when mannitol was used compared to microcrystalline cellulose. Thus, this Example demonstrates that mannitol increased the erosion rate of the tablet.

Example B5: Pharmacokinetic Study in Dog Model

This Example demonstrates the pharmacokinetic effects of administering the Formulation Fx (summarized in Example B3 above) and Formulations Fm and Fl to pentagastrin- or famotidine-pretreated dogs.

Pentagastrin pretreatment (6 μg/kg intramuscular injection 30 minutes prior to test formulation dosing) in fasted dogs was used to simulate fasting gastric pH in humans. Famotidine pretreatment (20 mg orally 1 hour prior to test formulation dosing) in fasted dogs was used to simulate human gastric pH when acid suppressant was co-dosed with test formulation. The results of this study are summarized in Table 9 below.

TABLE 9 PK data of the compound of Formula I tablet formulations in dogs F AUC0-24 Cmax Tmax Dog (%) (μM · hr) (μM) (hr) Dose (mg) Pretreatment Formulation Mean Mean SD Mean SD Mean SD 100 pentagastrin Fx 34 11 1.8 1.6 0.2 2.7 1.2 100 famotidine 0.2 0.06 0.01 0.02 0.002 1.7 0.6 100 pentagastrin Fm 13 4.1 1.4 0.8 0.2 1.8 0.4 100 famotidine 15 4.9 4.2 0.7 0.5 4.9 9.4 100 famotidine Fl 2.2 0.66 0.25 0.13 0.06 2.0 2.0

As shown in this table, for Formulation Fx, the exposure in famotidine-pretreated dogs decreased by more than 100 folds compared to in pentagastrin-pretreated dogs. In contrast, as seen in FIG. 11, Formulation Fm was observed to increase exposure in famotidine-pretreated dogs by about 75-fold. Furthermore, the exposure in famotidine-pretreated dogs was observed to be similar to the exposure in pentagastrin-pretreated dogs, which suggest that Formulation Fm could minimize the drug-drug-interaction with acid suppressants in human.

Example B6: Stability Studies

This Example demonstrates the stability of Formulation Fd, described in Example B2 above.

The physical stability of a bis-mesylate salt of Formula IA during processing was examined by powder X-ray diffraction (XRPD) and no form change was observed as shown in FIG. 4.

The chemical and physical stability of the tablets during storage was also studied. Ten tablets were packaged in each 100 mL high density polyethylene (HDPE) bottle containing 0 or 3 g silica gel desiccant. The bottles were capped with a polypropylene screw cap fitted with an induction-sealed, aluminum-faced liner. The bottles were kept at the following conditions: 25° C./60% RH, 40° C./75% RH, and 60° C. The tablets were analyzed by HPLC for chemical stability and by XRPD for physical stability.

As shown in Table 10 below, the tablets are chemically stable.

Ten (10) tablets packaged in 100 mL, white, high density polyethylene HDPE bottles containing three or zero gram Tri-sorb desiccant. Each bottle is capped using a white, continuous thread, child-resistant polypropylene screw cap with an induction sealed, aluminum-faced liner.

At 25° C./60% RH, no new degradants were observed while only RRT 1.29 impurity increased slightly. At 40° C./75% RH after 3 months, only 0.1% increase of total impurity was observed in the presence of desiccant while 0.2% increase was observed in the absence of desiccant. At 60° C. in the absence of desiccant, the stability was similar to at 40° C./75%. XRPD was performed at 3 month time point and no form change was observed (data not shown).

C. Solid Dispersion Formulation of a Bis-Mesylate Salt of Formula IA (“Formulation 2”)

The following Examples are directed to the solid dispersion formulation of Form 3, the monohydrate, bis-mesylate salt of Formula IA (such as the monohydrate thereof), which was prepared according to Example A above. It should be understood that solid dispersion tablet of the bis-mesylate salt of Formula IA may also be generally referred herein as “Formulation 2”.

Example C1: Spray Drying and Tableting Process

This example demonstrates the preparation of a tablet comprising a spray-dried dispersion of the bis-mesylate salt of Formula IA.

Bis-mesylate salt of Formula IA was combined with hypromellose 2910 and purified water, and spray dried, followed by secondary drying when necessary. The quantitative composition of the feed solution and resulting spray-dried powder is shown in Table 11 below.

Over the course of the feed solution stability experiment, the pH remained constant at ˜1.3 and no precipitation or gelling was observed. The spray drying process was assessed using an Anhydro MS35 spray dryer. Solid-state properties of the spray-dried powder are outlined in Table 13 below. All of the feasibility batches had similar particle size, water content, and high T_(g) values ranging from 135° C. to 140° C.

TABLE 13 Solid-state characteristics of the spray-dried feasibility batches Compound of Formula I: HPMC E3 Spray-Dried Characteristic Powder Particle Size Range 5-50 μm (PLM) Water Content (KF) 3-5% Bulk Density (g/mL)^(a) 0.27 Tap Density (g/mL)^(a) 0.31 T_(g) (mDSC) 135° C.-140° C.

The resulting solid dispersion (33.7% w/w of the compound of Formula I) was blended and milled with mannitol, poloxamer 188, crospovidone, and colloidal silicon dioxide, which was then blended with magnesium stearate, crospovidone, and microcrystalline cellulose and compressed to form a tablet.

Process optimization focused on the effect of two key parameters, compaction force and mill screen size, on the roller compaction process. Approximately 1.8 kg of intragranular powder blend was prepared and then divided into three sub-lots for roller compaction using different compaction forces (3 or 5 kN/cm) and mill screen sizes (1 or 1.25 mm) The following parameters were kept used: left smooth, right knurled rollers, 2 mm gap, and roller speed of 3 rpm. Final blends of each sub-lot were prepared and characterized for particle size, flowability by Flodex, bulk and tap density, and compression profile. The results are summarized in Table 14 and FIG. 8A.

When screen size was kept at 1 mm, the higher compaction force of 5 kN/cm resulted in larger mean particle size, higher bulk and tap density, and better flow. As shown in FIG. 8B, all of the blends were highly compressible.

The composition of this final formulation is listed in Table 15 below.

Tablets made with crospovidone eroded faster and showed faster dissolution rate in 0.01N HCl than those made with Ac-di-sol. Additionally, as shown in the table above, simple sugars such as dextrose and sucrose were observed to increase the erosion rate. The dissolution of the mannitol formulation (F1) and the dextrose formulation (F6) were compared using dissolution testing. FIG. 9 showed results comparing the incorporation of different sugars on dissolution rate.

As seen in the table above, during initial disintegration screening, it was observed that formulations containing Poloxamer 407 eroded slightly faster than those containing Poloxamer 188. Similarly, increasing the amount of crospovidone in the extragranular portion improved erosion rate. Formulation C was dosed in order to test the effect of incorporating a surfactant (TPGS) in the spray feed solution. Formulation D was prepared using Mannitol SD100 as filler and MCC102 in the extragranular portion to improve processability. The PK data presented in the table above shows that Formulation D resulted in the highest bioavailability in famotidine-pretreated dogs of the formulations tested. In addition, Formulation D was observed to have no pH effect.

Results outlined in Table 21 below show that the bioavailability of formulation D in pentagastrin-pretreated dogs was observed to be very similar to that in famotidine-pretreated dogs. Additionally, as seen in FIG. 11, Formulation D was observed to increase exposure in famotidine-pretreated dogs by about 100-fold.

This Example demonstrates the preparation of a spray-dried dispersion using a spray drying process.

A solid dispersion of a bis-mesylate salt of the compound of Formula I were prepared by combining polymorph Form 3, a monohydrate, bis-mesylate salt of the compound of Formula I with hypromellose 2910, and purified water. Additional methanesulfonic acid (in the quantities specified in Table 24 below) was added to the feed solutions to create solid dispersions with greater than two molar equivalents methanesulfonic acid. The resulting feed solutions were spray dried. The quantitative composition of the feed solution and resulting spray-dried powders is shown in Tables 24-25 below.

E. Other Studies

Example E1: Comparison of Intrinsic Dissolution Rates

This example compares the intrinsic dissolution rates of (i) a compound of Formula I (e.g., as a free base) (referred to in this example as Compound 1), (ii) a mono-mesylate salt of a compound of Formula I (referred to in this example as Compound 2), and (iii) polymorph Form 3, which is a polymorph of a monohydrate, bis-mesylate salt of a compound of Formula I (referred to in this example as Compound 3).

Intrinsic dissolution measurements were conducted using a rotating disk apparatus. Disks of Compound 1, Compound 2 and Compound 3 were separately prepared by directly compressing 100 mg of a powder of the respectively compounds in a die at a pressure of 2500 psi for 2 minutes using a hydraulic press (Carver Press, Fred Carver, N.J., USA). The exposed surface area for the resulting disks was 0.5 cm². A USP dissolution apparatus maintained at 37±0.5° C. was used for the dissolution study. Each dissolution vessel contained 500 mL of aqueous dissolution medium of 0.05 N HCl or pH 6.8 20 mM phosphate buffer with 1% cetyltrimethylammonium bromide (CTAB). The disk holder (die) was half-immersed into the dissolution medium and rotated at 100 rpm. Samples were withdrawn at specified time intervals and the amount of compound dissolved was determined by HPLC.

The amount of compound dissolved at each time point was plotted versus time and the observed dissolution rate (mg/min) was obtained from the slope of the plot. The observed dissolution rate was divided by the surface area of the compound disk (0.5 cm²) to obtain the intrinsic dissolution rate.

The results from this comparative study are summarized in Table 29 below.
